Abstract: A non-transitory computer-readable medium including a program causing a user terminal to realize functions to control progress of a video game is provided. The functions include: a displaying function configured to display a game image containing a moving object, a game field, and an operation object, the moving object moving in accordance with a virtual attractive force, the moving object being movable in the game field, the operation object being formed in the direction of the attractive force in the game field; a first action controlling function controlling an action of the moving object so that the moving object finally stops at a predetermined portion of the operation object; and a second action controlling function controlling an action of the moving object in a movement mode, the movement mode being determined in accordance with an input from a user when the moving object is in contact with the predetermined portion.

Abstract: A data file can be efficiently edited by a plurality of users. A source object is created from various data files, such as a structured document file or the like. A plurality of partial objects are created from a source object. A client terminal downloads a partial object corresponding to the data which a user desires to edit or read. When a client terminal which has acquired a right to edit, edits a local partial object, edit information showing an edit content is transmitted to a server apparatus. A source object is updated in accordance with the edit information. Further, while other client terminal is downloading the identical partial object, edit information, which is for reflecting an edit content, is transmitted to a client terminal.

Abstract: A method of adding a plug-in to a system, the method comprising sending a login request to a client. The login request is sent to an exclusive plug-in by the client. The exclusive plug-in, sends the login request to a server. The exclusive plug-in requests a certified plug-in list from the server on receiving a login success message from the server. The server sends a certified plug-in list to the exclusive plug-in module. The server, requests a plug-in list from the client. The client, sends the embedded plug-in list to the exclusive plug-in. The exclusive plug-in compares the certified plug-in list with plug-ins in the plug-in list. The exclusive plug-in notifies the client of a successful comparison. The client, notifies the user of a successful comparison.

Abstract: The namespace that is to be referred to for handling a document described in a markup language is identified. A namespace detection unit 310 reads out an XML document which is a processing target, and detects the line where the namespace has been described. In a case that the correct namespace cannot be identified, a namespace identifying unit 312 searches for and narrows down the namespace candidates while referring to a namespace information storage unit 316. Then, the plug-ins that correspond to the namespace candidates thus narrowed down are loaded. A candidate screen display unit 314 displays the display candidates created according to the respective plug-ins so as to allow the user to select one from among these display candidates. The namespace information storage unit 316 stores beforehand the relation between the character strings, such as tag names and so forth, which are used as a key for obtaining the namespace and which are described in a document, and the corresponding namespaces.

Abstract: Document management that offers improved ease-of-use is realized. A document storage unit 240 stores a document file to be encrypted. A document display unit 210 displays the contents of the document file on a screen. An encryption region specifying unit 214 allows a document editor to input data that specifies the region of the encryption target data in the document file displayed on the screen. A public key storage unit 242 stores public key data that corresponds to private key data held by document checkers. A checker level setting unit 216 allows the document editor to input data that specifies the access level for the encryption target data. A key search unit 232 detects the public key data that corresponds to the private key data of the document checker thus specified. An encryption processing unit 234 encrypts the encryption target data according to the public key encryption method using the public key data thus detected.

Abstract: To appropriately process data that is structured with a markup language. A DOM management part, when reading a large document, generates a DOM tree once before it saves part of the information included in the DOM tree to a storage device such as a hard disk. The DOM management part may determine whether or not to save information to the storage device by comparing the memory consumption of the source tree generated and the amount of memory remaining at the present time. The DOM management part may also select which information to save to the storage device based on the memory consumption of the DOM tree, the remaining amount of memory, the remaining amount of the storage device, the operating speed of a CPU, and the like. The DOM management part retains information indicating the tree structure in the memory, and saves information such as element names, attribute names, element values, and attribute values to the storage device.

Abstract: A data switching device includes a switch which performs a switch operation on data transferred via the data switching device. The switch forms a permanent link connecting terminals permanently. A charge information management unit manages charge information concerning a quantity of information transferred via the permanent link. A control unit sends one of the terminals a notification message including the charge information according to a predetermined sequence.
